Abstract
A graft preparation system includes a fixation implant including a strand of suture wrapped around a graft preparation card. A tenaculum includes a first arm having a first tooth and a second arm having a second tooth that are pivotally connected at a pivot. The first arm includes a slot between the first tooth and the pivot that receives the graft preparation card. A tape suture assembly includes a tape suture and a first suture strand. The tape suture is positioned on a graft, and the tape suture is attached to the graft with a stitch formed with the first suture strand.
Claims20
A graft preparation system comprising:
- a fixation implant including a button with a first button hole and a second button hole, a first strand of suture that passes through the first button hole, and a suture construct that passes through both the first button hole and the second button hole, wherein the suture construct includes a first free strand and a second free strand, and the suture construct includes a first adjustable eyesplice and a second adjustable eyesplice interconnected by a loop to form an adjustable loop;
- a graft preparation card substantially rectangular in shape and including a graft edge, an opposing tenaculum edge, a first cleat edge that defines a first cleat, an opposing second cleat edge that defines a second cleat, a passage having a longitudinal axis extending from the graft edge, a first hole and a second hole located on each side of the passage, a first slit that extends from the graft edge to the first hole, a second slit that extends from the graft edge to the second hole, a first groove on the graft edge located above the first hole, a second groove on the graft edge located above the second hole, a third groove located on the tenaculum edge, and a fourth groove is located on the tenaculum edge,
- wherein a line extending between the first groove and the third groove is substantially parallel to the longitudinal axis and a line between the second groove and the fourth groove is substantially parallel to the longitudinal axis,
- wherein the first strand of suture, the first free strand, and the second free strand of the fixation implant are wrapped around the graft preparation card,
- wherein the first adjustable eyesplice of the suture construct is received in the first groove and the third groove of the graft preparation card and the second adjustable eyesplice of the suture construct is received in the second groove and the fourth groove of the graft preparation card,
- wherein the first adjustable eyesplice is slidable through the first slit to be received in the first hole and the second adjustable eyesplice is slidable through the second slit to be received in the second hole, and
- wherein the loop of the suture construct is located between the first hole and the second hole;
- a tenaculum including a first arm having a first tooth and a second arm having a second tooth, wherein the first arm and the second arm are pivotally connected at a pivot, the first tooth and the second tooth are at a distal end of the first arm and the second arm, respectively, of the tenaculum, and the first arm between the first tooth and the pivot includes a slot that receives the graft preparation card;
- and
- a tape suture assembly including a tape suture, a first suture strand, a second suture strand, and a needle attached to the first suture strand and the second suture strand, wherein the tape suture is positioned on a graft, the first suture strand and the second suture strand extend from a distal end portion of the tape suture, the tape suture is attached to the graft with stitches formed by the first suture strand and the second suture strand, the first tooth of the tenaculum pierces a proximal end portion of the tape suture, the second tooth of the tenaculum pierces a proximal end portion of the graft, and the first suture strand and the two free strands of the suture construct wrap around a first cleat and a second cleat of the graft preparation card.
A graft preparation system comprising:
- a fixation implant including at least one strand of suture;
- a graft preparation card, wherein the at least one strand of suture of the fixation implant is wrapped around the graft preparation card;
- a tenaculum including a first arm having a first tooth and a second arm having a second tooth, wherein the first arm and the second arm are pivotally connected at a pivot, and the first arm between the first tooth and the pivot includes a slot that receives the graft preparation card;
- and
- a tape suture assembly including a tape suture and a first suture strand, wherein the tape suture is positioned on a graft, the first suture strand extends from a distal end portion of the tape suture, the tape suture is attached to the graft with a stitch formed with the first suture strand, the first tooth of the tenaculum pierces a proximal end portion of the tape suture, and the second tooth of the tenaculum pierces a proximal end portion of the graft.
A method of preparing a graft comprising:
- inserting a graft preparation card into a slot of a tenaculum, wherein at least one strand of suture of a fixation implant is wrapped around the graft preparation card;
- pivoting a first arm and a second arm of the tenaculum about a pivot such that a first tooth of the first arm pierces a proximal end portion of a tape suture of a tape suture assembly and a second tooth of the second arm pierces a proximal end portion of a graft;
- and
- creating a stitch with a first suture strand of the tape suture assembly to secure the tape suture of the tape suture assembly to the graft.
